Q: Given your focus on disadvantaged communities, why not start a more direct-service organization? Why do it through a social stock exchange?

DS: There is room for charities in the world, but I am interested in sustainable development, thus the interest in social enterprises – for-profit or not-for-profit companies focused on a social mission with a market orientation. They need to be able to attract investments for which they can give a return, and really show they can be financially viable as well.
